Barack Obama

2008 income: $2,656,902
Barack Obama's yearly earnings, though still high, have taken a considerable dip since he took office. Most of his revenue comes from the sale of his books, Dreams From My Father and The Audacity of Hope, as well as Of Thee I Sing: A Letter to My Daughters, a children's book.
